MAG Beta Gameplay Footage.

Reminds me of Battlefield 2, and that's a good thing!
Could be good but it depends very much on latency and, of course, what kind of players it attracts. A lot of potentially good online FPS' are ruined by being packed with insufferable players who act like asses (Halo 2 online springs to mind).
I think I'll stick to Team Fortress 2 for my online FPS needs to be honest.
